"The suspect had specific intentions to kidnap Jayme and went to great lengths to prepare to take her", the sheriff said, such as shaving his head to avoid leaving traces of identifying evidence behind.

Jayme's grandfather Robert Naiberg said in a telephone interview on Saturday that no one in the family knew Patterson.

"Jayme had a pretty good night sleep", Jayme's overjoyed aunt, Jennifer Smith, said in a Facebook post on Saturday.

Fitzgerald said officials did not yet know how she escaped, saying only that she had been released from the hospital and was being reunited with family. (But) he knew what he was doing. Kristin Kasinskas, one of the neighbours who took Jayme in after her escape last week, told The Associated Press that she was Patterson's middle school science teacher. Smith said she would see Closs on Friday afternoon.

Patterson's lawyers Charles Glynn and Richard Jones said in a statement they consider the situation "very tragic" and that they are relying on the court system to treat their client fairly.

He was scheduled for an initial court appearance Monday. The discovery ended an all-out search that gripped the state, with many people fearing the worst.

She said, 'I'm Jayme, ' the woman told CNN affiliate WCCO.

"There is a reunification process in place going on right now that includes medical mental evaluation, questioning by detectives and Federal Bureau of Investigation agents, and then reunification with family".

Smart called Closs fearless, strong, and a powerful survivor - but also says there is a long road ahead.

Sue Allard, Jayme's aunt, told local media she could barely express her joy on hearing the news.

Jake Patterson, 21, allegedly shot and killed Jayme's parents. She said she never saw Patterson on her street or in town, and doesn't remember seeing him since he was in high school.

Fitzgerald said Patterson had ties to Barron, Wisconsin, where Closs lived with her parents, but wouldn't elaborate.

Kristin Kasinskas said Jayme knew her captor's name, but the girl said she didn't know Patterson before he abducted her.

"At this time, nothing in this case shows the suspect knew anyone at the Closs home or at any time had contact with anyone in the Closs family", Fitzgerald said. "We don't believe he ... talked with them, had any digital footprint with them".

The sheriff said he didn't know whether Jayme had been physically abused.

He wonders whether Patterson was somehow stalking Jayme.

The cabin is in Eau Claire Acres, about 10 miles outside the tiny town of Gordon, in the dense evergreen forests of north-western Wisconsin. Law enforcement barricades blocked the road leading to the property Saturday.

Nutter said Closs appeared traumatized but in good physical condition, wearing an oversized sweatshirt and large shoes that were clearly not her own.

Police said they sent three teams to tell family members at various locations that she had been found, including one group that was attending a basketball game.

"He seemed like a quiet kid", she said.

He has no criminal record, the sheriff said.

The president of the Jennie-O Turkey store in Barron, where James and Denise Closs had worked for decades, said Patterson had been an employee for a single day three years ago.

Barron County district attorney Brian Right said he planned to file a criminal complaint against Mr Patterson next week.

Detectives pursued thousands of tips, watched dozens of surveillance videos and conducted numerous searches in the effort to find Jayme. They say she was "the only target". Smart was rescued nine months later after witnesses recognized her abductors on an "America's Most Wanted" episode.
